CALVIN R. DAVIS, OF SOUTH BEND, INDIANA, ASSIGNOR TO OLIVER CHILLED PLOWWORKS, OF SOUTH BEND, INDIANA.

PLOW. A

Specicaton of Letters Patent.

Patented July 14, 1908.

To all whom it may concern.'

Be it known that I, CALVIN R. DAVIS, of South Bend, in the county of St.Joseph and State of Indiana, have invented certain new and usefulImprovements in Plows; and I do hereby declare thefollowing to be afull, clear, and exact description of the invention, such aswill enableothers skilled inthe art to which it appertains to make and use thesame.

My invention relates to 'improvements in plows and more particularly ,toj ointer holders therefor,-one object of the invention being to providea jointer holder in which the vertical and lateral adjustments can beeffected independently of each other.

A further object is to provide a device of the character described whichshall be simple in construction; comprise few parts, and which shall beeasy to adjust.

A further object is to so construct a ointer holder that, when clampedto the plow beam, will not be liable to shift or change its positionunder heavy strain when at work.

With these objects in view the invention consists in certain novelfeatures of construction and combinations of parts as hereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation showing theapplication ofmy improvements to a ig. 3 is a similar view showing thelateral adjustment of the jointer.

My improved holder comprises a plate l, having in its central portion anenlargement 2, the outer face 3 of which is convex. Holes 4 5 areprovided in theplate or casting l above and below the convex enlargement2 and approximately in line with the respective en s of saidenlargement, for the passage of the arms of a U-bolt 6, by means ofwhich the holder is secured to a 4channeled plow beam 7. The free endsof the arms of the U-bolt are threaded for the reception of nuts 8 whichabut against the face of the plate or casting 1. The convex enlargement2 is provided with a vertical slot or opening 9.

through which the shank I0 of the jointer passes. This shank, andconsequently the pglow beam. Fig. 2 is a.

jointer, can be secured at any desired vertical adjustment by means of aset screw 11 passing through a boss l2 on the plate or casting l andenga ing said shank.

It will be seen t at byloosening one and tightening the other nut 8 onthe clamping U-bolt, the holder will be thereby rocked on the plow-beamand this will accom lish the lateral adjustment of the jointer an thelatter may be adjusted in or out of line with the landside of the plowbase as the case may require. Such lateral adjustment will be permittedon account ofthe convexbearing of the holder against the channeled plowbeam.

From the construction and arrangement of parts as above described, itwill be noted that the vertical and lateral adjustments are independentof each other, and this is important for the reason that whenthe jointeris adjusted in proper line with the plow base, said jointer may beraised or lowered as required without interfering with the lateraladjustment and vice versa.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,-

1. In a ointer holder, the combination of a plate or casting having anopening for the passage of the shank of a j ointer, means for securingsaid shank to said plate atany desired vertical adjustment, and meansfor adjustably securing the device toa plow beam.

2. In a jointer holder, the combination of a plate or casting providedon one side with a convex enlargement havin a vertical opening for thepassage of the s ank of a j ointer, means for securing said shank totheplate or castin at any desired vertical adjustment, said p ate orcasting provided with holes above and below said convex enlargement, aU-bolt having its arms passing through said holes, and nuts on the freeends of the arms of the U-bolt,l substantially as and for the purposeset forth.

3. The combination with a plow beam, of

a plate mounted to rock thereon, means forf securing said plate inposition, and means for securing a jointer shank to said plate at anydesired vertical adjustment. v

4. The combination with a ploW beam, of In testimony whereof, I havesigned this a plate mounted to rock on one side thereof', speelioationin the presence ol two subserib- 10 means for securing a jointer shankto said ing Witnesses. plate at any desired adjustment, and means 5engaging said beam and plate for rocking the latter and securing it tothe side of the beam Iitnesses:

to hold the vertically adjustable jointer at FRANCIS C. N IPPOLD,different lateral adjustments. A. A. FREDERICK.
